Abstract

The conventional cooling process was chosen because of the better estimation of manufacturing times and lower manufacturing costs. One alternative to minimize the decline in quality in plastic products is by using a conformal cooling process. This study will compare the contours of the fluid flow pattern between conventional cooling channels and conformal cooling channels. Case study on a box-shaped product made of PP material which has a melt temperature of 205 ° C. 3D product images were made with Solidwork 2017 software and process simulation using fluent 19.0 software. The results showed that the temperature flow pattern in the conformal channel resulted in a temperature absorption of around 303.2K while the conventional cooling channel was around 302.5K. Then the coolant channel that experiences high pressure drop occurs in the conformal cooling channel around 88888.9 pascals and the conventional cooling channel around 355555.6 pascals.

Abstract

The use of excavators across industrial and mining sectors is critical, particularly for bucket tooth components that perform penetration and excavation. These components often undergo wear and tear due to repeated stress and abrasion. This study aims to analyze the influence of variations in bucket tooth notch types on stress, strain, deformation, and safety factors using the Finite Element Method. The variation of standard, elliptical, and diamond notch types in the Komatsu PC200 bucket tooth model was designed using Autodesk Inventor Professional 2025. The simulation results show that the elliptical notch type has a maximum stress value of 6.2893 MPa, a maximum strain of 0.000036465 ul, and a maximum deformation of 0.00266049 mm, which is better than the standard and diamond types. Meanwhile, the diamond type has the highest maximum stress of 7.8416 MPa and the lowest deformation of 0.00259299 mm. The highest safety factor was found in the elliptical type (6.91635), which indicates that this design is safer to use in heavy workload conditions. The results of this study show that the elliptical notch type design is more efficient and has the best resistance to workload, so that it can improve the service life and performance of bucket teeth. The applied load represents a static reference for comparative evaluation among geometries; therefore, the results reflect relative design performance.
